These are FREE virus scanners:
avast! – (My personal favorite and recommendation)
Active Virus Shield –
(Powered by Kaspersky) Now “McAfee® Virus Scan Plus-Special”
Comodo AntiVirus – (Free for Home and Business users). I use to recommend this, but they haven’t updated it in a long time. Nothing feels safer than having an “up to date” scanner installed using definitions from last year.
ClamWin – Free and open source!
F-Prot for DOS – DOS scanner (last updated: 02/2005) No longer available!
Personally, I use the avast! virus scanner.
This bit of info was relavent back in September 2004, but should no longer be the case:
Using Windows XP SP2? Notice that some older programs wont work? (Stuff in DOS like EDIT.COM for example).
You may have an incorrect registry setting!
While looking for help, I found this thread on the avast! web site:
That thread lead to this thread, which had a fix:
I have a copy of the fix here:
Basically, the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\VirtualDeviceDrivers doesn’t point
to the correct file, preventing things from running (it’s supposed to point to the “aswMonVd.dll” file in your avast! folder).
More avast! Info:
Using Task Manager, you can identify the parts of avast! running on your system:
ashserv.exe is part of the on-access scanner.
ashmaisv.exe is the mail scanner.
ashdisp.exe shows the blue ball.
ashcmd.exe is the command line scanner (Pro version)
aswupdsv.exe is the part that checks for updates.
ashQuick.exe is Avast’s quick scanner.
