I made the mistake of letting someone else use my PC while I wasn't around to make sure they weren't going to do something unintelligent. Turns out, they clicked a link which forced Adobe Reader to open and install some kind of trojan. I instantly started getting random and fake "anti spyware" popups telling me I needed to buy such and such. I immediately ran malwarebytes, which found about 9 infected files, and deleted them. The popups stopped, but as soon as I rebooted I received a message, after the Windows boot up screen, but before the logon screen, that said wmiprvse.exe was not found, skipping Autocheck. I thought it was odd, but didn't think too much about it.
I noticed after that reboot that instead of the usual 4-5 svchost.exe 's that task manager picks up, I've been seeing between 7 and 8, with one or two running at a particularly high memory usage level. I thought that was odd too, but I wasn't sure what to make of it. Fast forward maybe 6 hours of normal usage, I got a sudden blue error screen for about 2 seconds, I didn't have any time to read what it said, but it forced my computer to reboot. This time, again after Windows boot up, but before the logon screen, I got an error message, but this time it said msln.exe was not found, skipping Autocheck. I've never seen either of these error messages before the virus so it's starting to get worrisome. I own up to date Norton Antivirus 2006, which is not picking up anything, and malwarebyte and adaware which are both up to date, and also not finding any errors.
The computer also will not boot up into safe mode now. I tried booting into safe mode but it simply won't let me, and reboots again when I try to enter in safe mode. I also noticed that after the 2nd reboot, I have about 1 GB EXTRA free space on my main HD now, which was VERY worrisome...but I can't for the life of me find what was deleted.
If anyone's got any ideas, I'd appreciate it much !
