McAfee False Positives? Or real trojans?

[darkfang77]

A friend of mine has been having a few problems with their computer lately, primarily, their browser keeps redirecting them to advert webpages instead of what he clicked on. He ran a full system scan through McAfee and this came up.

 

Question is, are these false positives? Or are they related? Similarly I found a PUP called "Crack-Style XP" which I deleted as well as a couple of viruses from a second scan on his computer.

 

Is anyone else having problems with redirecting browser? And how did you solve?

 

Thanks!

If every click directs to adverts and you already had some sort of viruses inside then I´d say PC is infected. Also you can check "manually" on task manager if there are some bizarre processes running, like names 09219809458.exe or firefox.exe has really wierd ID, memory usage etc.

My solution- reinstallation of OS if theres no important data to be saved. Installation max 2h > messing with 100 different antivirs(because 1 doesn´t delete all infections) min 5h.

That's the problem I'm having right now. That was the first hint that my computer had a virus. Only problem is none of the 3 virus scan's I have tried will pick up what I have. AVG has an update, but since my computer won't restart the correct way, it won't upgrade for me. So I'm f***ed on updating ANYTHING that requires a restart. What free virus scan's are there besides AVG, Malware Bytes, and Trend Micro Housecall?
