My avast runs less than 3,000 on my task manager before I had problems uninstalling it it was over 18,000. I don’t know if it’s working correct. I had the pro version, downgraded to the free version. IS something wrong? Also before my icon was not working with Avast. I think something is up. I know one day Avast was removing my virus and my computer died in the middle of the boot scan.
Hi and welcome to the Forum.
If you had a virus and feel something is up, I suggest you post on the Virus section of the forum and let one of our malware experts take a look.
