Hi Guys,
Recently, I mistakenly double clicked on a .scr file (I thought it was a video.. duh..)
Fully up to date Avast did not react when I downloaded it or opened it.
When I clicked it, nothing happened.. I soon realised my mistake & unplugged my network cable, then rebooted.. and started all kind of malware / virus scans (sideloaded via USB)
2 days later, I received a registered letter from my ISP informing me that my PC was infected with a worm / trojan and that I have 48 hours to react or they will disconnect me.
The timestamp on the letter where they started to detect suspicous activity was exactly the same time I clicked on the .scr.
I know this because I have the timestamp in the logs of adwcleaner which I ran right after I rebooted.
So.. basically, I have a 700mb .scr file which no malware or antivirus software seems to recognise.. but which is 99% certain to be infected with something.
Since then, I have done a clean re-install of windows.. because I didn't trust the PC any more!
But, I really want Avast to detect this so I can scan the other PCs on my home network (I want to find out if it managed to spread).
I just created a ticket with Avast, but I wanted to know if there is something else I could / should do?
Any advice?
Thanks
Will
