Virus warnings for the past few days

Since Monday at 2 pm, I've been getting warnings on Gamefaqs, Polygon, and CNET sites for some weird reason. I have an expired Kaspersky on my old laptop, which is the one that gets all these warnings. Whenever I load up a new page like clicking a topic or going into another board I get a warning of:

http://s.tagsrvcs.com/2/4.10.1/loaded.js//loaded

Then http://s.tagsrvcs.com/2/4.10.2/loaded.js//loaded that started yesterday at around 12:30

Saying it detects HEUR:Trojan.Script.Generic

It denies it every time but at this point I'm just surprised and annoyed how it still continues. Then I find out yesterday about the Adobe Flash problems and turn off Flash on all my computers right away, ALL of them use Firefox. So now I'm curious on what the problem even is. I'm pinning it on the Adobe Flash so far but nothing else.

@Robin_Mask: I get Trojans all the time.

Bare skin studded lol. On a serious note idk what kind of virus it is but if it's a Trojan that's not good. I would do a recovery or restore. Back before you got the virus, or back to factory settings. best bet would be to restore it back to factory settings. It will delete everything on your hard drive, except your operating system and the programs that are auto installed when you got your computer. You can always re download the programs you need though. Or use Nortans power eraser.

This is where it gets weird. Earlier this morning I got no warning from Gamefaqs. Then around 11 until now I had warnings. I just went back on again and it has no virus warnings.

@Robin_Mask: I'd still try one of the things I said. Better to be safe than sorry.

I already have Kaspersky on this and don't have extra ones... well at this point this PC is almost useless anyway. I would also like the opinions of others and curious on their thoughts.

EDIT: Interesting, I went to reports on Kaspersky and found that both trojans are loaded and inactive? I'm assuming they're not working?

EDIT 2: I just realized another weird thing. When the virus showed up Gamefaqs loaded for a bit longer, now the page loads completely and doesn't take the extra few seconds and no virus pops up.

@Robin_Mask: Option 1- Run a virus scan and see what pops up. If nothing pops up and you keep getting virus alerts or your computer seems like it's running slower. Option 2- Find a restore point right before you think you got the virus and restore your PC to that point you won't lose anything but what you downloaded after that. Last Option- Restore you PC back to factory settings. Will work like its brand new.

Those are your best options. Just trying to help you bro.

Don't worry, I know you have great suggestions. There has been no slowdown at all at any point or any weird problems.

The virus alerts have stopped and no slowdown. I might do the system restore if more problems continue but so far nothing and not sure if it might work?

System restore and restoring to factory defaults wont work if its well designed malware, just a heads-up.

@Robin_Mask: Boot into safe mode. Delete all cookies and uninstall anything you don't recognise.

Malwarebytes. Whenever an issue seems to pop up I run this program, it finds the culprit, and removes it. My antivirus Avast seems to do nothing for this type of issue.
