I run a full scan using the free AVG anti-virus about 2 weeks back and a few viruses were found.
1.) Trojan Horse Cryptic.AJC on C:\Programfiles\Nuance\PDFProfessional\PddfPro5Hook.exe
2.) Worm/Autorun.FR on D:\x.cmd
The above cannot be deleted and could only be moved to the virus vault. I called the guy who assembled the PC, who told me to re-format the PC. Recovery was softwares are locked in the D drive, the same drive the autorun worm was found. I did a re-format anyway.
After the re-format, I did a scan with AVAST anti-virus and no virus is found. In this instance, can I assume that the autorun worm is removed after the re-format?
Thereafter, I installed the Uniblue Registry Cleaner and LOTS (more than 300 errors were found). Can someone advise what causes these errors, since I had re-format the system. Are registry errors the cause of slow system?
I am also experiencing loading errors when I surf the internet as well as google redirecting (am using Firefox).
I did a full scan with Malwarebytes today and got the following results.
Can I safely have all these malwares removed by clicking the "Remove Selected" button?
TIA!
