Keyboard Repeat Rate & Location in "Regional and Language Options" keep getting reset everytime I start my computer up.
Long description:
I have been using Kaspersky Antivirus up until now and I update it quite often, but then I moved and didn't have the chance to update its virus list for around 2 weeks and accidentally got infected with the "gxvxc" virus. I tried to remove it manually like this:
S0. (System restore was automatically disabled by the virus)
S1. Booted into safe mode
S2. Used Unhackme (an anti-rootkit removal tool) to terminate the virus.
S3. Scanned (still in safe mode) for every possible malware using MalwareBytes Anti-Malware, and removed them.
S4. Delete traces of the virus: the fake Recycler, the virus's copies in system32, autorun.inf, in the Registry, startup.
S5. Uninstalled and reinstalled Kaspersky, because the virus somehow succeeded in preventing Kaspersky from running, Kaspersky was still able to start, but could not do a thing, let alone killing the virus. Updated virus list. Did a full scan.
S6. Booted into normal mode, ran Unhackme, Malwarebytes Anti-Malware and Kaspersky again, nothing found. Ran Windows Update (btw, I'm using XP SP2). Everything seemed to be OK.
But THEN:
P1. Keyboard repeat rate gets reset everytime my computer starts up. It's a nuisance having to scroll it back again to max speed.
P2. I can't change the Location and Standard in Regional and Language Options, it resets immediately after closing, for example: I change Location from US to Germany, hit "apply" then "OK", open "Regional and Language Options", it's changed back to US.
P3. Driver for integrated (Conexant) microphone seems to be messed up, sound input volume level is really low and I have to put my mouth (or any other sound emitting device) right next to the mic (I'm using a Lenovo T400) so that the mic can recognize the sound.
P4. Driver for mouse also seems to have been reverted back, but I fixed this already.
P5. I'm not sure about this but I think Windows takes longer to shut down than before, however, it still starts up quite fast, but sometimes hangs (quite rare).
P6. Settings for other applications, eg. Yahoo Messenger also gone, or folder options like "Show hidden files" became unchecked (Only once after being hit by the virus, I set them back)
I think this is a registry problem rather than an active virus, it is quite unlikely that my computer is still infected now that MBAM and Kaspersky are running normally again, however, it is still a possibility.
Many thanks in advance for reading and helping
