Why some viruses can be detected but not cleaned with the anti-virus software?
Anti-virus software not only detect viruses, but also other types of malicious codes, which may not be cleanable. For example, trojan horse is a type of malicious code that should be deleted instead of cleaned. In other cases, the virus may have corrupted the file and made it impossible to be cleaned / recovered. Nevertheless, there are some tips you can do to maximize the likelihood of recovering the file using anti-virus software: • Check whether the virus signature files and scan engine are up-to-date. • Make sure there is enough free space on the disk. • Check if removal instructions or automatic removal tool is available from anti-virus vendor web sites. • If still unsuccessful, obtain a virus sample and send it to anti-virus vendors for recommended actions.
