I am running AVG Free Edition as virus checker.Within the last three days, I have been getting a warning from AVG's Resident Shield stating that the folder 'System Information' is infected withe the Lovsan virus, and asks me to run AVG to remove it. Which I do, but the scan reports no virii at all!
I'm really at a loss what to do: what is the point of having a virus removal tool that first identifies a virus, then can't find or remove it?
It is probably in the system restore folder as I assume that you are using XP. AVG is an excellent tool but, like all the other AV's, it cannot delete from system restore. Go to start..accessories...system tools.... click the system restore tab and disable it.Reboot your computer, rescan and then turn system restore back on creating a restore point. (NB by turning off sys. restore and rebooting you will lose all your restore points). You could also go to the AVG virus vault and delete anything in there.
'I would lose ALL sysrestore points? even the initial one?'.......yes. You HAVE to delete all restore points, probably a good idea to get rid of them if your computer is running OK and start afresh.
'I update AVG EVERY day, so how did this thing get past it'....it takes a short amount of time for all AV companies to update their records during which you are exposed. Blaster was a particularly virulent one and evaded many AV's as it spread so quickly. If it is any consolation, an American oil drilling Co. that I do some work for was crippled by Blaster, in spite of having hardware firewalls and Government standard AV protection.;-)))) They were not best pleased. The patch from Billy Gates will prevent any further infections.
