Hi there,
During an Avast boot scan, Win32:Malware-gen was found in
C:\Users\Lina\Documents\To Be Deleted\800score.com GMAT Sample Tests\GMATV1f.exe
C:\Users\Lina\Documents\To Be Deleted\800score.com GMAT Sample Tests\GMATV2f.exe
C:\Users\Lina\Documents\To Be Deleted\800score.com GMAT Sample Tests\GMATV5f.exe
I deleted the files and did an Avast full scan afterward and found two files with Error: The file is a decompression bomb. (42110)
C:\Users\Lina\AppData\Local\Microsoft\Windows\Temporary Internet Files\Content.IE5\7JHTD5NE\SkypeSetupFull[1].exe|>[Emul]
C:\Users\Lina\AppData\Local\Temp\SkypeSetup.exe|>[Emul]
I couldn’t delete the files from the scan results window so I went to the folders manually and deleted the files. Then I installed Malwarebytes’ Anti-Malware and and followed the instructions I found on the stickied thread and the results came back clean.

I also installed OTL and tried to run it using the instructions in the stickied thread, but during the scan, it gave me the error “Cannot create file C:\Users\Lina\desktop\cmd.bat”. Should I be worried that it couldn’t finish scanning?
Also, to give some background, my laptop started running slower a few days ago. The transition from the starting windows screen to the welcome log in screen (Windows 7) went from less than a second to about 10 or 15 seconds. Ejecting my USB flash drives started taking 30 seconds - a minute or so. I also installed some font files as shortcuts, but after rebooting my computer, they disappeared from the fonts folder. Strangely, I can still use them in programs, like Adobe Illustrator. I was also prompted to back up a certificate (I think it was for the folder holding the original font files and the folder was also named in green text).
After I deleted the infected files and scanned with Malwarebytes, I ran a boot scan and full scan again, and everything showed up clean. I just want to make sure my laptop is virus/malware free and that this doesn’t come back to haunt me later on. Would it help if I tried to get a log from an OTL scan again? Are there certain things I can do to make sure my laptop is clean like cleaning out my temporary files? (I don’t know how to do this.)
Thanks a whole lot.
