I was receiving warnings again.
If a virus is replicant (coming and coming again), you should:
1) Enable/Disable System restore on
Windows ME or
Windows XP. System Restore cannot be disabled on Windows 9x and it's not available in Windows 2k.
2) Clean your temporary files. You can use the
Windows Advanced Care features for that.
3) Schedule a boot time scanning with avast. Start avast! > Right click the skin > Schedule a boot-time scanning. Select for scanning archives. Boot. Other option is scanning in
SafeMode (repeatedly press F8 while booting).
4) It will be good if you download, install, update and run other trojan remover tools:
a-squared and/or
Free AVG Antispyware (trojan removers). Some users recommend
SUPERantispyware or
Spyware Terminator.
5) Use the immunization of
Windows Advanced Care features of spyware/adware cleaning and removal.
However, the last item in the list was called a "decompression bomb" and it was located in a place on my hard drive that I am unfamiliar with.
Decompression bomb is a file that may be rather small, but decompresses to an enormous amount of data (when processed as a packed archive). Such file are not malicious per se, but they may block an antivirus program when it tries to scan them.
This kind of files is rather hard to detect (and avoid) precisely - so, it is possible that there are some false alarms. It's not a big problem in this case, however - the "decompression bomb" announcement actually means something like "The file has a very high, maybe even suspicious, compression ratio and the AV is not going to scan the archive content".
I'd suggest to ignore these files.
But you can change values into avast4.ini file to configure how avast should work with these files.

Here is the path of the file (note that the E drive does not contain the folder mentioned):
E:\System Volume Information\_restore{A2DF8360-4853-45B9-B89A-51D7E4D4A1BE}\RP162\S0044977.Acl\EXCEL.EXE
Maybe it's hidden just...
Follow the rule number 1 as I've posted above.
