Virus scan, virus scan?

I would like to know how to check for malware and virusses on my MacAir ...
Facebook tells me I am infected... is this for real???
Maurits

This is not real. That's probably a scam, so ignore it.
If you are worried about the MacBook safety, have a look at this website > http://www.thesafemac.com/mmg You don't need an antivirus, and I only recommend it if you have got files you will transfer to a PC, because you may infect other PCs even if the viruses don't affect to you (OS X can't get infected by Windows viruses).
Apart from that, if you still want to use an antivirus, get Sophos

Virus - can I scan to find out if I have one?

I just created a network by using a router [Apple product] to connect a new PC to my iMac for the internet. Because this PC has NO word processing of any sort [my husband thinks Microsoft should be sued], I wanted to download OpenOffice on it. Unfortunately went to a site that looked like an OO site and it wasn't - looked for all the world like it was OO. I did this yesterday when I was foggy tired and didn't pay close attention until I selected the "free download" and then when it was running realized it wasn't OO, so tried to stop it, but it wouldn't. Well, crossed my fingers and downloaded the real stuff. However, the damage was done. I had acquired a virus. I have a protection plan for the PC, so it is in right now - not really a big deal as I have nothing on it yet. Bought it at Best Buy and the guy said that lots of people get sucked into this scam.
Now for the question - Because my Mac was hooked up to the internet while this was going on in the PC, is there any way to find out if I am infected on the Mac? Should I buy something like WebRoot to scan for it and ferret it out if it's there OR is there some way I can scan on my Mac without it? I have no extra security protection. Am currently on Snow Leopard and have a download to upgrade to Mt. Lion. Don't know if this is dumb, but am afraid to upgrade until I know about this issue. If I do have a virus, don't want it to mess up things in the upgrade.

The good part is that you caught it right away and took action.
There is little likelihood of infection of a Mac OS X system with a virus from a Windows system. You can go to Thomas's site, http://www.thesafemac.com for ideas of things to do.
But be very cautious of any commercial Mac anti-virus software...most a very dangerous and damage Mac OS X. Never use Norton or McAfee as they are the worst of the worst, and an all costs stay away from MacKeeper and most of the "cleaning" programs.
You are probably ok, but if you feel you have to have something visit the Mac App store for ClamXAV, free and decent.

Had to reload drivers and updates for my HP scanjet G4050, I now enter image scan to scan photos but nowhere is there a "send" button to get them to iPhoto

Since loading Maverick and then, with the assist of Apple Support, I had to reload drivers and updates for my HP scanjet G4050, I now enter image scan to scan photos but nowhere is there a "send" button to get them to iPhoto.

Here are a couple of ideas:
1. (my favorite) - connect the printer to the router with an Ethernet cable for virtually the same functionality, more speed and fewer connectivity issues.
2. Reset by turning the printer off, holding # and 6 keys while and for a few seconds after turning it back on.

Virus scan / spyware scan deleting library?

I recently ran a full virus scan on McAfee Sonic Wall. When asked if I wanted to delete "potentiall unwanted programs", I just hit yes.
When I went to reload iTunes, my entire library was gone. I was able to re-import (but lost play counts and date added), but next time I opened iTunes, it said that the iTunes Music Library.itl file had been damaged.
Is there a connection here? Does anyone know how to disable the functions within Sonic Wall to stop it from messing with my Music Library file?

I seem to have solved the problem Swymer.
I was lucky in that I had a backup of my iTunes Music Library file pre-virus scan. Check around in other folders. I had a copy in the "Previous iTunes Libraries" folder.
Then do this:
1) uninstall then re-install your virus software. This was a real pain, but it was the only way for me to clear the quarantine logs and start over. McAfee had the iTunes folder flagged forevermore.
2) Delete all your old libraries, following the instructions in this document:
http://docs.info.apple.com/article.html?artnum=93313
3) Restart iTunes and let it do its thing.
That's it. I've got my music back. Back to living.
If you didn't have a library backup, don't despair. Your songs are still on your hard drive. It's only your Library files that are nuked; they're the roadmaps that tell iTunes how everything works.
If they are zapped, you may just have to rebuild your playlists & ratings using the "add folder" option.

Stopping anti-virus and anti-malware scans from scanning diasabled user files?

Using Windows Server 2008
If I only disable old user profiles, does anti-virus and anti-malware still scan their profiles and all files contained there within? Is this something that will happen regardless of the old users status and during a "whole computer" scan?
And if so, are computer resources still being used for these old profiles?
Thanks!

Hi LaEmperor,
From my experience with different AV softwares, I can say that they continue scanning them as part of the filesystem, despite of being disabled.
I am not sure about your question for the resources, but I´ll give two shots:
1. From the system perspective: basically affects the space that the files from that profile are using. The leave also some information on the Registry hive, on .USERS\ but unless it is a large numbre, I will not be concerned.
2. From the Antivirus perpective: Well, as usual, Disk I/O, RAM, CPU, etc...; so as much as disabled profiles, as much they will add to the usual amount of resource comsumption.
Hope you find this informative.

How to scan virus in MacbookPro?

recently i used a memory card that contained virus. how do i know that my macbook is safe? how to run virus scan in macbookpro?

Unless that memory card contained actual Mac malware, and you opened that malware after the memory card was connected to the Mac, you couldn't be infected with anything. If, as I'm guessing, the virus on the memory card was Windows malware, you're perfectly safe. You couldn't have opened it if you tried.

I have a ransomware virus on chrome browser that blocks use of browser How do I remove this virus. I scan with norton and shows no virus

I have a ransomware virus on chrome browser the blocks use of browser How do I disable virus?

It's likely the "FBI Moneypak browser hijack" which works by hijacking Javascript in the web browser so you can't escapte.
What you do is press command tab to get to the Finder, then from the Apple Menu select > Force Quit on Chrome.
Apple menu > System Preferences > General >
Uncheck “Restore windows when quitting and re-opening apps“
Apple Menu select > Shutdown, restart and don't start up Chrome.
Use Safari to find out how to disable loading of previous web pages in Chrome ( I don't use it )
Once Chrome loads, then Reset it's caches etc.
If you know the domain name of the malicious site, then feed it here

Email Hacked and Comcast wants me to download Norton Anti Virus to run scan

My email was hacked and I contacted the ISP (Comcast) they said to download Norton Antivirus and run it on my iMAC then go in an change my email password. I use Microsoft Outlook for my email or I read it on my iPhone 5. Should I use Norton? I read something that said it doesn't get along with the new OS for my iMac (just downloaded it around 2 months ago).
Getting ready to start changing all my passwords for stuff but want to know if I should run the Norton Antivirus.
Help please.

Obvioulsy someone at ComCast did not hear you say you owned a Mac. They can be very Windows-centric. It is unlikley that a virus caused a hacked e-mail. A lot of that happens at the server level (Comcast in your case) and has nothing to do with your computer.
Norton has casued many more problems for Mac owners than it has fixed. Run away.

Firefox doesn't load my banking website but other browsers do even after virus and malware scan and cookies & cache cleared

I have cleared cookies and cache, scanned with Panda and still can't load my banking website. I can load the website with any other browser I've tried with no problems.
This is with Firefox in safe mode and in regular mode.

It sounds as though you have worked through this article: [[Firefox can't load websites but other browsers can]].
Do you notice any difference between secure sites and non-secure sites in what error message you get?
Do you use any kind of content filtering or parental control software?

AIM virus? "Virus-detection" popups in Safari?

Could it be, some sort of virus on my beloved macbook pro? Here is the story..
Last night when I logged into Adium, I received a message from "aim" claiming that I had some sort of friend request waiting for my approval, and someone wanted to list me in their profile. I hovered over the link and it went to the aim website, and curiosity always kills the cat.. I clicked. (Dumb, right?) Well, it did take me to the aim website and it was asking for my log in, so I closed.
Since then the same IM pops up every time I log on. I'm not sure if that has any affiliation with my next problem, but it could be useful information. I went to myspace.com, and I received a pop up saying something along the lines of "Malware/Spyware has been detected on your computer and you should resolve it by going to this website and downloading our anti-virus software." There was a URL at the top, not sure where it went to because it didn't matter. I canceled out because I had no other option, and it came up again. I canceled once more, and it came up again with only OK as the option. I tried force quitting Safari, and it didn't work at first. I received yet another pop up talking about slow script, asking if I wanted to continue to run it, and I said no, then hit apple alt esc and managed to close Safari.
Everything seems to be working fine in Firefox. Any suggestions as to how to rid of whatever might be happening, or any information on what it is at all would be greatly appreciated, I am not sure where to start. I'll be the first to admit that I an a novice when it comes to this sort of thing. Thank you for your help. I will be happy to give anymore information if needed.

Yes, sites like that (Adium, FaceBook, YouTube) are notorious for being the prime sources of 'scareware' and malware, most of which is aimed at Windows users and extracting unnecessary money from them with pointless, worthless software. No malware can affect your Mac unless you allow it to install, which in most cases would require your root password.
In your case you may have acquired a 'tracker cookie' sending you to other sites than you intended.
To get rid of them you ned MacScan:
The appearance of Trojans and other malware that can possibly infect a Mac seems to be growing, but is a completely different issue to viruses.
If you allow a Trojan to be installed, the user's DNS records can be modified, redirecting incoming internet traffic through the attacker's servers, where it can be hijacked and injected with malicious websites and pornographic advertisements. The trojan also installs a watchdog process that ensures the victim's (that's you!) DNS records stay modified on a minute-by-minute basis.
SecureMac has introduced a free Trojan Detection Tool for Mac OS X. It's available here:
http://macscan.securemac.com/
The DNSChanger Removal Tool detects and removes spyware targeting Mac OS X and allows users to check to see if the trojan has been installed on their computer; if it has, the software helps to identify and remove the offending file. After a system reboot, the users' DNS records will be repaired.
(Note that a 30 day trial version of MacScan can be downloaded free of charge from:
http://macscan.securemac.com/buy/
and this can perform a complete scan of your entire hard disk. After 30 days the cost is $29.99. The full version permits you to scan selected files and folders only, as well as the entire hard disk. It will detect (and delete if you ask it to) all 'tracker cookies' that switch you to web sites you did not want to go to.)
A white paper has recently been published on the subject of Trojans by SubRosaSoft, available here:
http://www.macforensicslab.com/ProductsAndServices/index.php?mainpage=document_general_info&cPath=11&productsid=174
Also, beware of MacSweeper:
MacSweeper is malware that misleads users by exaggerating reports about spyware, adware or viruses on their computer. It is the first known "rogue" application for the Mac OS X operating system. The software was discovered by F-Secure, a Finland based computer security software company on January 17, 2008
http://en.wikipedia.org/wiki/MacSweeper
On June 23, 2008 this news reached Mac users:

More information on Mac security can be found here:
http://macscan.securemac.com/
The MacScan application can be downloaded from here:
http://macscan.securemac.com/buy/
You can download a 30 day trail copy which enables you to do a full scan of your hard disk. After that it costs $29.95.
More on Trojans on the Mac here:
http://www.technewsworld.com/story/63574.html?welcome=1214487119
The latest news on the subject, from July 25, 2008, is:
Attack code that exploits flaws in the net's addressing system are starting to circulate online, say security experts.
The code could be a boon to phishing gangs who redirect web users to fake bank sites and steal login details.
In light of the news net firms are being urged to apply a fix for the loop-hole before attacks by hi-tech criminals become widespread.
Net security groups say there is anecdotal evidence that small scale attacks are already happening.
Further details here: http://news.bbc.co.uk/2/hi/technology/7525206.stm
A further recent development is the Koobface malware that can be picked up from Facebook (already a notorious site for malware), as reported here on December 9, 2008:
http://news.bbc.co.uk/newsbeat/hi/technology/newsid_7773000/7773340.stm
There may be other ways of guarding against Trojans, viruses and general malware affecting the Mac, and alternatives will probably appear in the future. In the meantime the advice is: be careful where you go on the web and what you download!

Officejet Pro 8600 e. Problem scanning from Scan and Capture App in Win 8.1

Officejet Pro 8600 e. New.
Installed on HP Envy 23 Touch. Running Windows 8.1.
Wireless set up. Prints fine. Problem is scanning from the HP Scan and Capture Software App in Win 8.1
Using Scan and Capture App I can scan photos fine. They come out clear. Scanning documents in GRAY has multiple bands/lines in gray over the entire page running vertically. Scanning documents in COLOR are fine.
Also, if I scan from the printer directly using the touch screen on the printer, the scan output is fine.
I did the Scan utilty to discover any errors and it did not show any. I think it's a software error. I am going to uninstall the HP Scan App and then reinstall. So, I will do the uninstall/reinstall and report back.
Also, I would like to know if there is a desktop program for scanning? I would prefer to use that instead of the Modern HP Scan and Capture App.
Thanks....

Hi artrum,
I understand you've been experiencing issues scanning from your Officejet 8600 using the Windows Scan and Capture program. I will certainly do my best to help you with this!
From what you've explained, I believe you're correct, it does seem like it's an issue just with the Windows Scan and Capture program and as you've been able to scan from the front panel of the printer you definitely have the HP software installed. What I'd like to do is have you use the HP Scan software, where you should no longer run into issues.
To access the HP Scan software and be able to access it easily from your desktop I'd like you to follow the steps below:
1. Go to your start screen and just start typing File Explorer. You should be able to then open it to access your computer's files.
2. Then open Local Disk (C: ), followed by Program Files (x86), followed by HP, then HP Officejet Pro 8600, followed finally by bin.
3. In the bin folder you should see HPScan. You will want to right click on HPScan and go to Send To and then select Desktop.
Now you should see HP Scan on your desktop and be able to open it and scan through that application.
Hope this helps, have a great day!

HP Laserjet M1319f MFP scaner not scan continues pages.

Hi. I am using HP Laserjet M1319f MFP ALl in one printer & scanner software. Previously installed in windows 7, scanner function works, it will scan multiple docs in one pdf or one file. But now i have windows 8.1 installed. I have install the Printer / Scaneer software & firmware as suggested by HP site download. Print and scan working ok, but unable to scan the document in one file, it will not ask as previously do you want to scan another page or not? so is there any settings / software available that i can do the continuos scan in one file. Thanks,Bhautik Shah

Hi,While a Full Feature software was available for Windows 7, a such no longer provided for Windows 8. A basic set of drivers as offered only provide basic scan capabilities using the OS utilities, a such does not offer an HP Scan Utility and allow scanning a single file only. Try the 3rd party NAPS scan utility below, it offers PDF and multiple page scanning and offered as a freeware:http://sourceforge.net/projects/naps2/files/latest/download Within that app you may scan multiple pages prior saving the PDF. Hope that helps,Shlomi

Full Table Scans / Index Scans /Index Organized Tables...

Can anyone give me an example where an index would be the best option to query 99% of data.
Can anyone give me an example where a FTS is the best option to query 1% of data.
If IOT are better in terms of performance and also in terms of saving storage space then why cant we always use IOT in the database . Why do we need to follow the regular table and index to store data.
Responses are appreciated !

It's easiest to consider extreme cases for thought experiments:
Can anyone give me an example where an index would
be the best option to query 99% of data.
The obvious case would be where you had an order by clause with a matching index. With a well-clustered table, the optimizer might decide to do an index full scan to collect 100% of the data in order rather then doing a tablescan and sort.
In fact, with first_rows_1 optimization, and certainly with first_rows optimization before it, you would sometimes see the optimizer use such a strategy to read 100% of the data in the right order, discarding 99% of it, rather than selecting 1% of the data through a more precise index and sorting it.
Can anyone give me an example where a FTS is the
best option to query 1% of data.
Consider a table in a tablespace with an 8Kb block size - with short rows (roughly 80 bytes) you can get 100 rows per block. Run a query that wants to get one row from each block (i.e. 1% of the data). A tablescan with a db_file_multiblock_read_count of just 2 would be more efficient than an indexed access. For a more realistic example consider picking one row from every 16th block when your db_file_multiblock_read_count is 128.
In fact, if you check what Oracle does when you sample 1% of the rows using the sample clause, you may see cases where it actualy uses multiblock reads to scan the whole table, discarding the blocks it doesn't want.
