Answer 1

Before we move on, please read the following points carefully.
First, read my instructions completely. If there is anything that you do not understand kindly ask before proceeding.
Perform everything in the correct order. Sometimes one step requires the previous one.
If you have any problems while following my instructions, Stop there and tell me the exact nature of your problem.
Do not run any other scans without instruction or add/remove software unless I tell you to do so. This would change the output of our tools and could be confusing for me.
Post all logfiles as a reply rather than as an attachment unless I specifically ask you. If you can not post all logfiles in one reply, feel free to use more posts.
If I don't hear from you within 3 days from this initial or any subsequent post, then this thread will be closed.
Stay with me. I will give you some advice about prevention after the cleanup process.
Absence of symptoms does not always mean the computer is clean.
My first language is not english. So please do not use slang or idioms. It could be hard for me to read. Thanks for your understanding.
Multiple Antivirus Programs installed!
I do not recommend that you have more than one anti-virus product installed and running on your computer at a time.
The reason for this is that if both products have their automatic (Real-Time) protection switched on, then those products which do not encrypt the virus strings within them can cause other anti-virus products to cause "false alarms". It can
also lead to a clash as both products fight for access to files which are opened again this is the resident/automatic protection. In general terms, the two programs may conflict and cause:
1) False Alarms: When the anti virus software tells you that your PC has a virus when it actually doesn't.
2) System Performance Problems: Your system may lock up due to both products attempting to access the same file at the same time.
Therefore please go to add/remove in the control panel and remove either
Microsoft Security Essentials or McAfee.
