Question

Anyone that can help me remove some nasty malware/viruses?

Apr 12, 2015 7:20PM PDT

I was recently cleaning my sisters laptop from all the regular junk people get their computers infected by.

She was not using any kind of anti-virus or anti-malware so there is a lot of junk, and formatting the pc is not an option at this moment.

Anyway i install programs like Kaspersky Total Security, Malwarebytes Anti-Malware, Norton 360, Avast and ESET to remove the junk.

One after the other (waiting for the previous to finish and then restart PC) i use each of these programs to perform the most thorough scan possible (including tweaking settings for maximum "paranoia").

To cut the story short, these programs removed A BUNCH of junk but there is still some crap on the laptop that NONE of those programs are detecting!
Neither the manual scanning nor the "constant system protection" of these programs are able to detect the obvious malware!

I can manually delete the folders of these junk/malware but it reappears either instantly or after a restart.
Sometimes they are in a form of a firefox/chrome plugin/addon, but at other times they are just regular malware that does various annoying things (mostly ad related).

So how can i get rid of all such junk, aside from a full pc format, when all the best anti-virus/malware programs have miserably failed?
Is there any way to combat these horrible malware that seem invisible to every form of scanning PC security programs have to offer?

Remove malware/viruses
May 9, 2015 1:01AM PDT

When a virus infected to a PC it is a very very difficult to remove. In many cases not possible.

What actually happen is, viruses create bunch of it own copies in many places of your PC to survive.
All of those copies work as its original one and always try to maintain the number of its copies in the PC.

Virus Guards normally scan your hard disk from one end to another. In that process they scan one area for one time (1 folder only once)
When the virus guard delete a virus file, it cause to reduce the amount of virus copies. When it happens other virus files (which are still not scanned) immediately take actions to make there own copies again and they will created in scanned folders.

Due to that process it is not possible to delete some viruses after the infection.

Take a look at Grif's link, it can be very helpful. One thing, however, when running a scan with Malwarebytes, run the scan in Safe Mode with Networking ....not just Safe Mode...there is a difference
