I have a Toshiba Laptop, windows 7 OS. During the past 2 days my computer suddenly got incredibly slow, can barely open folders without them freezing.
When i open task manager on the whole it says its barely using memory, and cpu stays under 25%, except for the occasional spike. Iv gone through the prgrams running and dont see anything suspicous.
I ran malwarebytes and kaspersky scans, with nothing.(by the way i have kaspersky as my virus protection.) Then i ran rkill, and it stops the virus. Temporarily. After a restart things get slow, then slower, then back to where i started. Same with combofix, my computer was great and then it slowed and slowed untill it was a slug.
Now, the first time i ran rkill a window popped up saying Pev.exe has stopped working. When i ran rkill later i didn't get that message, i haven't seen it since.
And a really odd thing happens, when the computers really slow, and i open a folder there a application call " pev ". After rkill does its thing its gone. i have seen it in 2 folders so far, but when i go back its gone. Also, the date there created is minutes before i open the folder.
request the combofix log and ill post it.
Any ideas would be much appreciated, i have never seen anything like this.
