Hello,

I have noticed some changes in my laptop for at least a month, but I am not sure what is causing these changes.

Starting up used to be fairly quick, but now it takes at least 30 sec between the time I see my desktop background and the time I can choose an Internet connection. Also, sometimes when I try to access websites like Wikipedia, my Internet browser will simply stop. However, closing the programs using the task manager seems to take care of the problem. I do remember seeing popups of Windows 7 Antivirus 2012 once in a while, so could it be the source of my problems (if they are problems)? I've never clicked on these popups, but maybe they installed themselves on my laptop?

I did see the removal instructions for Win 7 Antivirus 2012, but I'd like to make sure I am doing the right thing, especially since the MBAM log looks clean.

Thank you very much for your time, it is really appreciated! :thumbup2:

I was not able to find the log for the ESET online scanner, but no threats were found apparently. I used the default setup so the archives were not scanned. Should I repeat this step and scan the archives as well?

Starting up the computer still takes a very long time (which is kind of unusual since it used to be so quick), but I haven't seen a Win 7 Antivirus 2012 popup yet. Does it mean that my laptop is malware-free? I was afraid that the malware had downloaded itself to my computer.

I do not find any suspicious entries in your startup

Download

TFC


Launch it,it will close all running programs

click on START,it should ask for reboot

Turn off your system restore,restart the PC,create a new restore point

http://windows.microsoft.com/en-US/windows7/Turn-System-Restore-on-or-off


Update your antivirus frequently,do not click on suspicious links

Safe surfing :)
