I am Addas, a new member to your forum, I searched for best Malware Removal site, and I found your forum .
My computer* is highly-infected as I think, Let's begin, My laptop is 3 years old, I use it daily for internet, programming, and gaming. Last 8 months it become too slow, so I used Speeding programs to speed up my PC like Registry cleaners, junk cleaners, and etc. . Last 4 months, my anti-virus (Kaspersky Internet Security), anti-malware (Malwarebytes' Anti-Malware), and anti-spyware (SUPERAntiSpyware) detected 47 viruses/malwares/spywares/adwares in total (I deleted the log). Last 2 weeks, my PC always freezing and not responding like when I name/rename something, everything do the same action, so I do a repair install, this was working until last week, the same problems happened, I scanned with my anti-virus, anti-malware, anti-spyware and nothing detected! This corrupt my hard disk, so I bought a new one and restored the backup! and the problem didn't go! So I use it with freezing till today's morning, I was cleaning my PC with Advanced SystemCare 5 and I found 2 KEYLOGGERS! when I deleted them, my computer become in mess, I download new windows update and requested a Disk Doctor and found one error with Advanced SystemCare 5, I didn't know what to do in freezed computer so I tried to restarted my computer in Safe Mode, but the Safe Mode freezes, I forget that I request a checkdisk , and install the updates, so my computer restarted and made a checkdisk and found 5 issues, it restarted again and made a failure windows update, restarted again and requested a checkdisk again, but this time it is too slow, and the same thing happened but much slower! so I used to shutdown the computer with the shutdown button,
and my computer is working in freeze (Not Responding) mode, so I tried to backup the hard disk but it gives me an error "A Volume Shadow Copy Service component encountered an unexpected error. Check the Application event log for more information. (0x80042302)." which is in event viewer "Volume Shadow Copy Service error: Unexpected error calling routine GetProviderMgmtInterface. hr = 0x8004230f, The shadow copy provider had an unexpected error while trying to process the specified operation." so I made a sfc scan using command prompt, it found errors and fixed it, but the major problem didn't fix, and I came here. Any help will be appreciated!
P.S: After the 47 viruses/malwares/spywares/adwares I removed my anti-malware,and anti-spyware and changed to Bitdefender Anti-virus plus, and before that my computer thinks I turned off a fake anti-virus called PC Cleaners Pro.
P.S 2: I think the keylogger took some info from my computer as the junk files were 1 GB, so I didn`t use internet anymore in my infected PC, so I transfer info and files by a flash disk
P.S 3: I end task manager processes to give more CPU like explorer.exe
*P.S: I uses Windows 7 Ultimate service pack 1 (build 7601) in a laptop (Notebook) (Acer Aspire 4935G)
