Computer began to slow down.
-multitasking is impossible: for example playing mp3 file and small avi file= 100%CPU spikes,
audio is stuttering, and according to process explorer, in these moments "hardware interrupts" are up to 20-30%
What happen before:
-I installed K-lite codec pack
-New version of Flash player tried to update and failed.
-According to Event Viewer, I've got many errors depicting hard disk.
I found suggestions to check cables and clean dust from inside.
When I defragmented hard disk and cleaned all the dust these errors didn't appear again.
But in SMART info there is warning in "Ultra DMA CRC Error Count" field.
What I have already done:
-jqs.exe process disabled (Java Quick Starter - it writes to disk very often)
-scan with: Avast, Malwarebytes, Hijack this
-disabled few processes in autostart
-uninstall K-lite codec pack
-uninstall Flash Player
What seems strange:
When I try to make scan with HitMan Pro, few seconds after scan begins,
HitmanPro notices about "possible infection of TDS/TDSS rootkit- Alureon/Olmarik"
(something like "The device stack of the hard disk is referencing to hidden driver") and computer immediately reboot.
When I tried to run HitMan Pro in safe mode, scan performed normally, but it didn't found any TDS rootkit.
Do you have any ideas what is wrong?
Is it malware, disk, or audio codecs?
(sorry for my English:)
