CAV (both 1.1(?) and beta 2) causes excessive disc activity when I run certain programs such as Sidekick99, Thunderbird, Notepad, MSHearts, and others. As long as these programs are active the disc access starts slowly and eventually the disc begins to thrash and only stops thrashing when I close these programs. This does not happen with all programs.
Also, some windows and/or programs close automatically.
The OS’s are WinXP pro - sp1 & sp2.
Removing CAV does not alter the situation - the damage is done. Whatever settings CAV changed/affected, they are now permanent. The only recourse is to re-install the OS, which I have done 2 times now. At first I thought the problem was caused by a virus. I then thought that maybe it was a hardware fault. Doing all the requisite checks and after carefully monitoring the program re-installations I have localized the fault to CAV.
Has this been reported before? Is there a fix? I hope so, 'cause I really like the program.
I could forward you some of the output from FileMon if I hear from you soon enough. I’ll be re-re-reinstalling XP shortly (without CAV…)
HI pfred,
The hards disk uses/interaction may increase if you install any AntiVirus with on-access scanner/real time monitor. This is because, it monitors disk for any kind of changes in files or file’s execution. But, if you two AntiVirus or AntiSpyware(with Realtime monitor), the disk access will be much more due to multiple scanning of same file by each product.
Unfortunately it was a bug attack (virus) that was not detected by COMODO ver. 1.? nor ver 2 beta, called EXPIRO.C, I presume a variant of EXPIRO.A

It constantly traverses all disks to infect every exe file it finds and that is why there is constant disc access. So if you have more than one program running the disc starts motorboating… In the end the system becomes almost unusable. Kind of a stupid virus - but very harmful. The bug was finally detected by AVG Free.
