Yes. You will only have the most current RP that you created yourself after cleaning the system as it is now.
If I do the disk cleanup, will -all- system restore points be removed, including those that were
made -before- the infection?

Microsoft Security Advisory (967940): Update for Windows Autorun
...Disabling Autorun functionality can help protect customers from attack vectors that involve the execution of arbitrary code by Autorun when inserting a CD-ROM device, USB device, network shares, or other media containing a file system with an Autorun.inf file...

Yes. When an anti-virus or security program quarantines a file by moving it into a virus vault (chest), that file is essentially disabled and prevented from causing any harm to your system. The quarantined file is safely held there and no longer a threat until you take action to delete it. One reason for doing this is to prevent deletion of a crucial file that may have been flagged as a "false positive" especially if the scanner uses heuristic analysis technology. Heuristics is the ability of a scanning program to detect possible new variants of malware before the vendor can get samples and update the program's definitions for detection. Heuristics uses non-specific detection methods to find new or unknown malware which allows the anti-virus to detect and stop if before doing any harm to your system. The disadvantage to using heuristics is that it is not as reliable as signature-based detection (blacklisting) and can potentially increase the chances that a non-malicious program is flagged as suspicious or infected. If that is the case, then you can restore the file and add it to the exclusion or ignore list. Doing this also allows you to view and investigate the files while keeping them from harming your computer. Quarantine is just an added safety measure. When the quarantined file is known to be malicious, you can delete it at any time.
Is it enough to just delete it as instucted by AVG there and reboot?
You should always scan USB Flash Drives after they have been used in other computer systems, even your own. Another easy way to do this is to download "ClamWin Portable Antivirus", put it on your USB Flash Drive, update its definition files and perform a scan.
Should I also run all the software mentioned in this thread on that usb drive just in case?
