avast suddenly disabled - virus?

Avast Free Antivirus / Premium Security
1

I’m on Vista SP2, the avast on-access scanner’s automatically boots on startup.

I went to this website and Avast detected a trojan and I assume, blocked it. After that, just to be safe, I rightclicked the ‘a’ icon and selected avast antivirus to do a scan. While I was setting up the parameters (type of scan etc), there was some lag and I may have extra clicked some button on the antivirus screen, then a blurb popped up to inform me that on-access control was disabled. I clicked on the blurb which led me to Windows Security Center and was able to reactivate the scanner, much to my relief.

I got the antivirus scan running now, however, I’m wondering whether it was due to a possible trojan or my random clicking or something else that the on-access providers were disabled?

Thanks!

If it let you re-enable the on-access scanner, I doubt that you have a virus. When you visit a website that avast is warning you about, it’s a good sign, and chances are that avast prevented the bad code from running in the first place.

I’d just run a scan of your system with avast to make sure nothing got on your system. Delete your temporary internet files, and after that, run a quick scan with malwarebytes.

You probably won’t find anything.

If you do, post back here and let us know about it.
